To separate business logic from UI rendering in React components, apply the Epic three-layer architecture. This pattern enforces UI-only components that delegate logic to dedicated hooks, ensuring predictable and testable rendering.

The Epic three-layer architecture for React frontend development is a structural pattern that strictly separates UI rendering from business logic. It enforces UI-only components, explicit props interfaces, and hook-based logic separation to create consistent page components.

To enforce data-testid attributes for testing readiness in React UI widgets, generate components using the Epic three-layer architecture. This approach mandates data-testid attributes and test-friendly patterns, preventing direct server actions or data fetching within the UI layer.

Yes, the Epic three-layer pattern works for refactoring existing React components. It enforces UI-only rendering and hook-based logic separation, stripping direct server actions or data fetching from components to establish clear prop interfaces and architecture consistency.

React page components should avoid direct server actions and data fetching to maintain architecture consistency. Delegating this logic to hooks ensures UI-only rendering, making components predictable, explicitly prop-driven, and ready for testing.
